SPECIFICATION forming part of Letters Patent No. 729,265, dated May 26,1903. Application filed November 12, 1902. Serial No. 130,979. (Nomodel.)

To all whom it may concern:

Be it known that I,'PETER B. BRAZEL, a citizen of the United States,residing at Oheboygan, county of Cheboygan, State of Michigan,

have invented a certain new and useful Improvement in Snow-Plows; and Ideclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

My invention relates to snow-plows; and it consists in the construction,arrangement, and combinations hereinafter fully described, and pointedout in the claims.

In the drawings, Figure 1 is a'perspective View of the entire plow asarranged for. service. Fig. 2 illustrates the front section of the same.Fig. 3 is a sectional view through the attachment of Fig.2 to 'the mainbeam or tongue. Fig. 4 illustrates the attachment of the rear beam ortongue. Fig. 5 is a perspective view of the rear section. Figs. 6 and 7are perspective views of the details of said rear section. Fig, 8 is aperspective view of the central section with one of the moldboardsremoved. Fig. 9 is a side elevation of the right-hand side of Fig. 8.Fig. 10 is a rear View of the left-hand side of Fig. 8 with themoldboard and attachments illustrated but detached therefrom.

Similar characters refer to similar parts.

In the drawings, A represents a pilot-sled with the usual runners andwhich is adapted to carry the front end of the device. To this isattached in the ordinary manner a tongue B, which has the usualattachments adapted for connection therewith of the proper team. Aboutthese matters there is nothing new whatever, and therefore they are notfurther illustrated or described.

Swiveled to a cross-beam connecting the runners of the pilot-sled is amain beam or keel C, which extends rearwardly entirely through all ofthe three removable sections ofthe plow. To this is attached by means oflifting and lowering the screws the forward section of the plow. (Shownin Fig. 2.) An intermediate or middle section, through which this beampasses, is shown in Fig. 8, and a rearward section is shown in Fig. 5.Each of -D (shown in Fig. l'in dotted lines) with a stirrup-strap Dextending from the bottom end of the bolt back to the beam D. At theopposite extremity of the beam D means are afiorded for attachedwhiftletrees W on the under side thereof by means of a bolt and strap inthe usual manner, to which whiflietrees a team may be attached, the beamending with a seat S, and as the details of construction are unimportantand familiar it is not necessary to fully describe them. It is obviousthat'the attachment of the beam D enables another team of animals to beemployed, the services of which are very important, as

they are able to follow the track made by the plow, doing the majorityof the work to the best advantage, leaving the pilot-team attached tothe tongue B to do the breaking of the road and the steering only. Thewhole rear connection is sustained upon the runners R R, attached to therear section. (Shown n. F s- Passing now to the details of the diiferentsections, that shown in Fig. 2 consists in a triangular structure made,primarily, of three pieces 1, 2, and 3. Pieces 1 and 3 are united at theapex 4 and cut down so as to leave an opening wide enough to insert thebeam C and in which opening it may move vertically. Pieces 1 and 3 arealso armed with flanged iron edges 5 and 6, so that they, together withthe edges, operate somewhat in the nature of a moldboard to break theway. In this sense it constitutes what might be termed a pilotsection. Aplatform consisting of two pieces 7 and Sis firmly fastened to thetriangular section 1, 2, and 3, and the rear piece 2 is cut down, so asto permit of the location of the beam 0 therein with the capacity ofvertical movement.

The whole section of Fig. 2 is raised and lowered or adjusted withreference to the beam 0 by means of screws inserted in the nuts 9 and10, the nut) being firmly fixed in the apex of this pilot-section and 10being centrally located and firmly fixed to the piece 2 and directlyunderneathandtransverselycentral of the main beam (.1. The screws whichengage these nuts are passed through the main beam. They are marked 11and 12. They are fashioned with collars l3 and 14 on their shafts, sothat they are longitudinally fixed, but rotatable in the beam 0. Hand-Wheels are furnished for these screws, whereby they may be rotated bypersons located on the machine, and it is obvious that by rotating themthe whole sect-ion (shown in Fig. 2) may be raised and lowered at eitheror both ends with reference to the beam 0, and there fore the loweredges of the side pieces 1 and 2, carrying the flanges 5 and 6, can beadjusted with reference to the work that is to be done.

Passing now to the second section, (shown in Fig. 8,) this isrigidly'but removably attached to the main beam by bolts 15 16, passingthrough cross-pieces 17 18. The section consists of two wing-boards 1920, united by the cross-pieces 17 18 and also by a cross piece 21. Twoplatform parts 22 23 are so located that between them is left a channelfor the main beam 0, the parts afiording braces resisting twistingstrains. It will be noted, therefore, that this section is rigidly butremovably connected to the main beam instead of being adjustablyconnected.

The cross-bar 21 carries at each end longitudinally fixed but rotatablescrews 24 25 in a similar manner to those already described, 11 and 12.These may be operated by handwheels by attendants located on themachines. Thesescrews 2425, operating through nuts 32 on plow ormoldboard sections 26, of which one is shown, 2b, in Fig. 8, (thecorresponding one, 27, being omitted from that figure, but is shown inFig. 10 detached,) afford means for raising or lowering the moldboards.

On the side plate 20 is firmly attached a metal plate 28, havingundercut edges 29 29. The landside 30 of the moldboard is formed withrentering lips 31 31, which engage the undercut grooves 29 29, and thusallow the moldboard and landside, fixed together, to be vertically movedand adjusted, whereby twisting strains or detaching strains are firmlyresisted. These moldboards 26 27 have depending points 28' somewhat atan angle to the general level of the machine and the lower edge of thelandside 30. These points 28 28 may be adjusted so as to cut grooves inthe frozen surface underneath the general lower plane of the plow, andas they are properly adjusted as to width between nloldboards 2e 27 thetongues cut these grooves properly for the purpose of affording tracksfor lumber-sleds in case the device is used for the purpose of clearingout lumberroads, it being found much better to have tracks for suchpurpose, so that the runners of the sleighs can follow without slidingfrom side to side, than to leave a plane surface.

The rear section is illustrated in Fig. 5. It consists of the runners RR, united by crosspieces 33 34, upon which planking is attached, 35 35,leaving a longitudinal space or groove, between which is inserted themain beam 0, which is firmly but removably bolted to the cross-pieces 3334. The front of this section is closed byavertical cross-pieceextending over the top of the beam 0 and at right angles thereto,(marked 36.) To this piece are hinged by hinges 37 the wings F F. Theseare adapted to fold closely up to the sides or be spread out and bracedby the adjustable braces G G. Each of these braces is made of twopieces- 38 39. Piece 38 is hinged at 40 to the runner R, and piece 39 isattached by dowel-pins 41 41 to the wing F by inserting the pins in theholes 42. By swinging the wing F olf and disengaging the dowel-pins theadjustable brace can be tolded in against the runner and the wing, thenfolded in and held by a book 43, engaging in an eye 44. Pivotallyattached to the braced section 38 is a bail 45, and this engages thesectional part of the brace 39 in a slot 46, cut therein, and byswinging the bail outwardly slightly it can be relieved from the slotand placed in another slot, and so on, thereby adjusting the length ofthe brace as a whole. As these braces are alike, it is only necessary todescribe one of them, the only variation being rights and lefts. Inorder to add to the stiffness of the brace and make it onlylongitudinally adjustable, a slot is cut in the portion marked 38 at 47,and a bolt 48, working in the slot, is fixed in the piece 39. As alreadystated, the side pieces R R of this section act as runners inconjunction with the pilot-sled A.

The operation of the device is apparent from the foregoing description,it being obvious that the adjustment can be made of the front section orof the moldboards or of the wing-pieces F F of the various sections,respectively, whereby both the depth of the cut or grooving and thewidth may be adjusted respectively, the forward plow cutting away thecrust of snow in the center of the road, the central section, withmoldboards, cutting out the track, while the wings of the third sectiontake up the snow and turn it off one side clear of the track.

It is obvious that various changes in the construction and arrangementsof the parts could be made and substituted for those shown without inthe least departing from the nature or principle of the invention. It isalso obvious that constructing the snow-plow as awhole in the separableparts, as described, it fulfils all the conditions necessary forefiicient work under all circumstances and is readily separable forloading on other vehicles for transportation in a compact form.

What I claim is- 1. In a snow-plow, the combination of a pilot bob-sled,a central rearwardly-extending beam, a front vertically-adjustablesection attached thereto, a central section having vertically-adjustablemoldboards also attached thereto and following the vertically-adjustablefront section, and a third section having runners and adjustable wings,substantially as described.

2. In a snow-plow, the combination of a pilot bob-sled, atcentralrearwardly-extending beam, a front vertically-adj ustable sectionattached thereto, a central section having vertically-adjustablemoldboards also attached thereto and following the vertically-adjustablefront section, a third section having runners and adjustable wings, anda rearwardlyextending tongue pivotally attached thereto and adapted tobe used as a means for attaching power, substantially as described.

3. In a snow-plow, the combination of a central rearwardly-extendingbeam, a verti- 'panding wings and carried upon runners, substantially asdescribed.

In testimony whereof I sign this specification in the presence of twowitnesses.

PETER B. BRAZEL.
